Recently, a fundamental limit for antenna radiation efficiency was proposed in [1] . Although valid for most antenna applications, a clarification is needed with regard to the fundamental limit expressed by [1 eqs. (14) and (15)] . This clarification is to draw the attention if one like to extend (14) and (15) to cylinders with radius in the range of skin depth. However, it does not invalidate the original work since the skin depth was assumed to be much smaller than the thickness of the object. This point was initially raised by J. Cahill from Technology Service Corporation.Recently, a fundamental limit for antenna radiation efficiency was proposed in [1] .
